You can get a sense of the level of craftsmanship of this house and the quality of the restoration. It feels a little less fussy with our stuff in it, though there is still much to do. As an interesting aside, the hallway chandelier was a gift from Mark Andes (Spirit) to the woman who restored the house.

    Wow, beautiful, Bill! Love the wood work!

      Bill, This is what you need!

      A Isoclean Zero Ohm Power Panel.....

      I bought it because I wanted to go extreme and after I hooked it up and it had time to settle in I would not want to be without it.

        Can someone explain what a audio grade ISO transformer is opposed to an industrial one ?

          It is 10 times as costly, ha.
          (I'm sorry, couldn't resist)

        I remember seeing your photo montage of the installation, Greg. That is a beautiful piece- no isolation transformer as part of it?
        I'm "invested" in the Equi=Tech which I got at a bargain price, but having been storing it for several years, I'm now not so sure. I need to get it down here first, perhaps I will sell it.

          There is no transformer on the Zero Ohm Power Pannel.
          However that was a conscious decision on my part, I live in a rural area on some land and there is a huge (5'w x 3'd x 3'h) power transformer on the edge of my land feeding my house. After consultations with my electric providers engineers it became apparent that adding any transformer to that huge beast would be a waste of time and money. All I needed was a new dedicated line from the big ass transformer to the new Isoclean job with a new meter and all. I then added 3 six foot ground rods placed in the earth for a super ground and all was fantastic.

          Your choice may be different based on your homes individual power situation.....

          I'm not sure (yet) what my power looks like in this new location, though my suspicion, given urban density, leads me to conclude the worst. (There is a large mid-century condo/complex next door, but thankfully, I don't come off their transformer).
          For the first phase of this project, I'm simply augmenting the power to the main house-- there, all breaker boxes are outside, given the construction--no basement, circa 1880's pier and beam design.
          I was considering installing the Equi=Tech in a separate outbuilding that I will have to construct-- and for which I believe I'll be able to get a separate service path. That's where something like the IsoClean would make sense. Call that Phase II.
          Living in the country has its advantages-- I had very clean power up along the Hudson north of Manhattan.

        Al- to the extent I used that terminology, I was referring to equipment that isn't marketed to the audiophile community (often with commensurately high prices), but instead, just industrial/commercial electrical gear. For example, in my discussions with one electrician/audio enthusiast, he recommended a large EI isolation transformer which is a fraction of the cost of a toroidal. It is used in stadiums and commercial set ups, and meant to be installed outdoors in a large weatherproof case. I know toroidal are preferred because they are quieter and throw off less stray "junk" but I gather the performance of a big traditional EI transformer is pretty good--only question I have is possible high frequency roll-off.

          I was just wondering
          mine is 10k
          208 in parallel secondary at 125 volt.
          Copper windings and is epoxy sealed rated for outdoor but sits below my panel. It does not hum loud enough to hear it with electric closet closed. Just wondering what more can there be
          that panel you posted is panel porn wow does that look great. Custom I assume lol. Is the copper buss gold plated
          ? Stainless steel encloser to.

            In getting to where I am I tried things many ways after I setup the system. Two things I learned in my room
            one interconnects longer than 6 feet needs to be balanced
            second was grounding and hum are not the same meaning you can have no hum and bad sound and not so bad and hum. It may sound dumb but it was very repeatable. What I did is not NEC compliant but yielded the best sound. It's completely isolated from everything after the ISO
            grounds are starr to one spot in audio power panel
            regrding rolled off highs yes this is true but it led me back to grounding not the ISO
            I had three different brands and types lol. As I am winding down now I look no forher but enjoy others concepts
            that panel is amazing looking.

              The newest Isoclean Zero Ohm (that I bought) has an all new non magnetic case that was implemented to offer a better sound.
              The case is built quite thick and robust plus it locks with a special locking mechanism that really secures the panel.
              It doesn't come with any holes pre-drilled in the chassis I had to drill my own mounting holes, I also insulated the panel with blocks of Mpingo wood custom cut between the chassis and the wall studs, worked out great.

              Also an important thing (I believe) is that the Zero Ohm uses 100% gold plated Seimens 32a breakers!
              That does add some headroom to the power delivery, plus I am feeding the panel 100a for just 3 outlets.

                Bill (or Greg), any link to that montage?

                  It's been an expensive week here at the ranch. The electricians are pulling cable. We are doing a Controlled Power isolation transformer (10kVA) which will be mounted on its own slab in the back of the house, with a 4 gauge feed to a Cutler-Hammer breaker box upstairs (copper buss bar), that will distribute power via 10 gauge romex to a series of dedicated outlets. I bought a pile of Porter Ports in gray, and found some nice red nylon covers from Hubbell. I'm hoping the wiring will be finished this week, though we are still going to be waiting for the transformer.
                  I just ordered a matched quad of GEC KT-66 for my old Quad II amps that will run in the vintage system I have planned for the living room. That's still a work in progress.

                  Next up, gotta order the Minus K and stand.

                  And this is still a stop gap til I can go to phase II and build a separate building.

                  I've done some research on silencer boxes for my compressor and came to the conclusion that the best one will be DIY, so that's in the offing as well. (I plan to hire a cabinet maker to built it, but I'll supply the more esoteric sound proofing materials). James at Silentaire in Houston has been a great resource, as usual.
                  More as it happens.

                  Just in case you may not know the Quescent current of the 10 k in amps may be 5/7 amps. No load mine is about 5. That good bill every month and it's why I switch the whole thing off

                    What's the downside of killing the power to it if not in use for period of time? I guess the transformer would have to re-energize, and perhaps that stress isn't good in the long run, don't know. The price of admission I suppose. Along with appliances that spy on you.

                      Real NOS GEC KT-66 tubes or Russian KT-66 tubes that say GEC? I have had the original Quad II amps in my system several times over the years that are owned by a friend of mine. Each amp has all real NOS tubes in it including GEC KT-66 output tubes (clear glass-not the smoked glass) and those amps kick ass.
                      SP-10 MKII table with custom power supply designed and built by Peter Noerbaek, SME 312S arm, Dyna XV-1S cartridge, Zesto Andros 1.2 phono stage, Otari MX-55 tape deck, Ampex 350 repros, ARC Ref 6 pre, ARC Ref 75 amp, and NOLA KO speakers with a pair of Def Tech Ref subs.

                        Uhm, real ones. Did I make a mistake?

                        I was at one time running the ten k ISO into two P10 REGEns and two amps
                        or stopped when I got a 300 bill. My standby current was over 14 amps 24 hours a day. Shutting it off and on has no effect only the circuit breaker may wear in time. Amps and preamps warm up in about 30 mins or so tube stuff faster. Dacs are also in need of warming up as well. Some claim longer. Good luck and I am truly happy for you and your new setup.
